That second evening they shut the cat and her two kittens into the shed just as carefully as before. In the morning only Spotty was left! The speckled little Popocatepetl had vanished, too!

[CHAPTER X—RUTH SEES SOMETHING]

The mystery of the vanishing kittens cast a cloud of gloom over the minds of the younger Corner House girls. Besides, it had rained in the night and was still raining after breakfast. It was a dull, gloomy day.

“Just a nice day for us to start cleaning the garret,” Ruth said, trying to put cheer into the hearts of her sisters. “Only Mr. Howbridge, who has been away, has written me to come to his office this forenoon. He wants to arrange about several matters, he says. I’ll have to go and we’ll postpone the garret rummage till I get back.”

“Poor Sandy’s all wet and muddy,” said Dot, who could not get her troubled mind off the cat family. “Just as though she’d been out in the rain. But I don’t see how that could be. She’s washing up now by the kitchen stove.”

They had brought the mother cat and Spotty into the kitchen for safety. Uncle Rufus shook his head over the mysterious disappearance of Petl, Almira and Bungle, too; whispering to Mrs. McCall:

“Do look for sho’ as though rats had got dem kittins. Dunno what else.”

“For goodness sake, don’t tell me there are rats here, Uncle Rufus!” exclaimed the widow, anxiously. “I couldn’t sleep in my bed nights.”

“Dunno whar you’d sleep safer, Mis’ McCall, ter git away from ’em,” chuckled the old colored man. “But I exemplifies de fac’ dat I ain’t seed none ob dere tracks.”

Occasionally Uncle Rufus “threw in a word” in conversation which sounded euphonious in his own ears, but had little to do with the real meaning of his speech.
